' QQMBINED FIRE-Por AND T WYERQIRON.

10 @LZ whom it mag/concertar Be it known that I, CHARLES 0. SwENsoN,

a citizen of the United States, residing at Minneapolis, in the countyof Hennepin Aand 5 State of Minnesota, have invented certain neWanduseful Improvements ina Combined FireePot and Twyer-Iron; and'I dodeclare the following to be a full, clear, and eXact description oftheinvention, such as will enable 1 1o others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to l the figures of reference markedthereon,which form a part of this specification.

i5 My invention relates to blacksmiths forges.

It has special reference to the parts known to the tradeand art as thenre-pot andthe twyer iron, and the main objects are,

first, to provide an improved combined twyerzo iron on lire `pot;`second, to further improve upon the construction set forth in my UnitedStates Patent No.v 792,179, issued on the 13th of June, 1905, partly bysimplifying and cheapeningthe sameand partly by emz 5 bodying importantfeatures which by misunderstanding and errors were omitted from saidapplication and patent. These and other objects I attain by the novelconstruction and'arrangement of parts illustrated in 3o the accompanyingdrawings, in which-f Figure 1 is atop view of my improved repot andtwyer-iron. Fig. 2 is a vertical -central sectional view of same on theline a a in Fig. 1. Fig. 3 is a top view of the upper flange 3 5 12 ofthe tWyer-iron.

of the twyer-iron, showing the means by which the ashes and cindersarelet out from the ashpan. Fig. 5 is adetail top view ofthedraftregulator.

4o n Referring tothe drawings by referencefnu# l merals, 1 designatesthe fire-pot, whichis cfa v substantially circular concaveform, With twodiametrically opposite depressions 2 anda central-blast opening y3,below which is a `45 hemispheric concaveli, in which is' mounted von ahorizontal rocking rod or shaft 5 a sub-v stantially globular body ordamper 6,' pro. vided-v'vith'pra'cticall central-blast openings 7,Lforming a centra blast, While .collars 8 I 5o aboutthe rock-shaft holdythe damper in al f vcentral* position in the cavity 4,y so thatpractically all around the damper is-formed a side blast, which incombination with the 'center blast forms avery -eective blast, producing-5 5 the most efficient fire.` Said fire-pot is also specification ofLettersratent.

formed with a base-flange 9, which is so large that it`holds thefire-pot very'steadily'` ported upon the surrounding bottoni' `or base10 ofthe forge or hearth thereof. In my forn mer patent above referredto said flange was so'small that it had-t0' rest .on sup ortingbars,which involved more expensefboth in i material and labor than to simplymake ,the flange wider; At the under side of said flange l9 .areprovided'in circular order yguiding-liigs l,6.5 1 1, between which is,centrally guided .the upperflange 12 *cfa vertical .cylinder orltuhe153, having a lateralk branch 143,`through which it f receiveswindfromthe blower. (Not shown.) i

Said tube 13 is suspended from the'flre-pot 7o` by the bolts 15,inserted in holes 16 in the latter and in quadrantal slotsy 17 in theflange- 12, so that the position of the depressions .2 in the fire-potmaybe changed from a longitudinal to a transverse position withreference 75 to the rock-shaft 5 or thetube 14.- Y

. In Fig. 3, 18. designates grooves in lthe flange 12 for the shaft y5.n f

The lower end of the tube 13 has at one side a lug 19, to which ispivoted a horizontally- 8o swinging lid 20, having a handle 21v stoppingagainst and normally resting in a hook 22, formed upon the opposite sideof the tube. Said lid serves as the outlet for asles and cindersaccumulating inthe lower half of the 8 5 'tube 13. The purpose of thedepressed portion 2 2 is to form a valley for tires and other irons ofsome length to get them in proper position in the fire- It will beobserved that although the flange 9o 9 is wide enough to answer thepurposes described the structure -is still inexpensive,

since the flange only connects with the firepot by a reduced neck 23. Itwill also be understood that the valve or yblast-regulator 6 cave inthelowerpart thereof, of alhorizon- 1o 5 .tally-arranged rock-shaft and asubstantially centrally perforated blast regulating piece mounted on theshaft in said concave in such a manner that van opening for side blastis formed betweenthe valve and .the fire-pot, 11o`f .ile-pot having inits upper edge diametri@- vally opposite depressions and in its bottombolts extending down through said slots and being provided with nutsbelow the flange 12, said fire-pot also having a central openingdirrectly over the blast-regulator and a iiange adapted to rest upon thehearth of a forge and hold the tube 13 suspended in an open- Y ingtherein.

3. The combination with the vertical tube 13 having the side inlet 14and means for closing its bottom end, of the upper flange 12 formed onsaid tube and having oppositely# disposed quadrant'al slots and thegrooves 18, a rook-shaft in said grooves and a erforated valve-piece orblast-regulator on t ie shaft, a lire-pot having in its upper edgediametricallv opposite depressions and in its bottom bolts extendingdown through said slots and being provided with nuts below the iange 12i said fire-pot also having a central opening directly over theblast-regulator and a flange adapted to rest upon the hearth of a forgeand hold the tube 13 suspended in an opening therein, said iire-pot alsohaving at its bottom side guards engaging the flange 12 to help hold thetube in'oentral position.

In testimony whereof aflix my signature in presence of two witnesses.
